Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Like Fig. 4 and shown in Figure 5, according to the first embodiment of the present invention, the scroll compressor sealing configuration comprises housing 20; Upper cover 10, envelope is located at housing 20 open upper end places; Moving scroll 203 and fixed scroll 204 are arranged in the housing 20, have the intermeshing roll bending that is the swirl type curve and forms; Breathing pipe 205 passes upper cover 10 and is arranged in the housing 20, and breathing pipe 205 is arranged on the upper-end surface of fixed scroll 203, between the counterface of breathing pipe 205 and fixed scroll 203, is provided with Sealing.
In the present embodiment; Breathing pipe 205 is arranged on the upper-end surface of fixed scroll 203, therefore, need not consider that breathing pipe 205 cooperates with side between the fixed scroll 203; And only need consider that the end face between them cooperates; And the sealing effect of Sealing, effectively reduce difficulty of processing, simplified processing technology.Sealing is an O-ring seals 214 here, and O-ring seals is simple in structure, and is easy to use, and sealing is reliable, and applicability is wide, can effectively reduce cost.This O-ring seals 214 is set in place in the counterface of fixed scroll 203 is the mount grooves 220 on the upper-end surface of fixed scroll 203; Mount grooves 220 also can be arranged on the counterface of breathing pipe 205; Because mount grooves 220 is arranged on the end face junction, processing is more prone to, and machining accuracy also is easy to guarantee; Can reduce difficulty of processing, improve installation efficiency.
From Fig. 5, can see; Breathing pipe 205 in the present embodiment is connected on the suction port 231 of fixed scroll 203, uses as the housing sucking pipe, preferably; The suction port 231 concentric settings of breathing pipe 205 and fixed scroll 203; Make to get into the gas stress equalization in the suction port 231, flow to evenly, can keep stable fluidised form.More preferably; The breathing area of breathing pipe 205 is less than the section area of suction port 231; When gas when breathing pipe 205 flows into suction ports 231, can not run into the obstruction of suction port 231 place's tube walls, can the build-up of pressure loss; Also avoid causing air turbulence, have a negative impact owing to air-flow and tube wall bump against.
As shown in Figure 5; Sealing configuration according to present embodiment; Preferably, the internal diameter A1 at the counterface place of breathing pipe 205 and fixed scroll 203 is less than the internal diameter B1 of O-ring seals 214, and the outer diameter A 2 at the counterface place of breathing pipe 205 and fixed scroll 203 is greater than the external diameter B2 of O-ring seals 214; In such cases; At first can reduce the rigging position precision that radially reach circumferencial direction of breathing pipe 205, can reduce the positional accuracy of the ventilation pore of upper cover 10 indirectly, improve installation property and processability at loam cake; Secondly can reduce the positional accuracy that radially reaches circumferencial direction of the mount grooves 220 of placement O-ring seals 214, improve processability at fixed scroll 203; When breathing pipe 205 during, can reduce the conformity at center, hole with the inlet hole center of fixed scroll 203 of breathing pipe 205 once more, improve the installation property with fixed scroll 203 assemblings.
When compressor operating, O-ring seals 214 is because of exhaust high pressure after compressing and the generation of the pressure reduction between air-breathing low pressure distortion, and the gap realization of filling housing breathing pipe 205 and fixed scroll 203 seals.
As shown in Figure 6, the installation steps of the breathing pipe 205 of present embodiment are: welding upper cover 10 and housing sucking pipe (being breathing pipe 205); O-ring seals 214 is placed in the groove 220 of fixed scroll 203 upper surfaces; The housing sucking pipe is combined with fixed scroll 203, weld upper cover 10 and housing 20 then.In combining operation, the device of decision housing sucking pipe and fixed scroll 203 positions relation is a positioning and guiding bar 221; Positioning and guiding bar 221 comprises: the axial region of interior slotting housing sucking pipe; Be formed on the contact segment of upper end-hole of an end, the contact housing sucking pipe of this axial region, and be formed on this axial region the other end, be connected to the abutment portion on the end face of end face or support of moving scroll 204 at the place of direction straight down of housing sucking pipe.Position relation with 221 pairs of housing sucking pipes of positioning and guiding bar and fixed scroll 203 positions; Promptly confirmed the relative position relation between upper cover 10 and the housing; According to this position relation upper cover 10 is welded on the housing 20 then, accomplishes the installation of sealing configuration.
Like Fig. 7 and shown in Figure 8, according to a second embodiment of the present invention, compare with above-mentioned first embodiment; Its difference is; Breathing pipe 205 is connected the air outlet 232 of fixed scroll 203, and with these air outlet 232 concentric settings, the breathing pipe 205 here is to use as outlet pipe.Preferably, the breathing area of breathing pipe 205 is greater than the section area of air outlet 232.When gas 231 when flowing into breathing pipes 205, can not run into the obstruction of breathing pipe 205 place's tube walls from the air outlet, can the build-up of pressure loss, also avoid having a negative impact because air-flow and tube wall collision cause air turbulence.
As shown in Figure 8; Sealing configuration according to present embodiment; Preferably, the internal diameter C1 at the counterface place of breathing pipe 205 and fixed scroll 203 is less than the internal diameter B1 of O-ring seals 214, and the external diameter C2 at the counterface place of breathing pipe 205 and fixed scroll 203 is greater than the external diameter B2 of O-ring seals 214.
When compressor operating, O-ring seals 214 is because of exhaust high pressure after compressing and the generation of the pressure reduction between air-breathing low pressure distortion, and the gap realization of filling breathing pipe 205 and fixed scroll 203 seals.
As shown in Figure 9, breathing pipe 205 installation steps of present embodiment are: welding loam cake 10 and outlet pipe (being breathing pipe 205); O-ring seals 214 is placed in the mount grooves 220 of fixed scroll 203 upper surfaces; Outlet pipe is combined welding loam cake 10 and housing 20 with fixed scroll 203.In combining operation, what decision outlet pipe and fixed scroll 203 positions concerned still is positioning and guiding bar 221.
According to scroll compressor of the present invention, comprise above-mentioned scroll compressor sealing configuration.
From above description, can find out that the above embodiments of the present invention have realized following technique effect: the breathing pipe of scroll compressor sealing configuration is arranged on the upper-end surface of fixed scroll; Between the counterface of breathing pipe and fixed scroll, be provided with Sealing; The Sealing mounting groove easy processing of this sealing configuration, simple in structure, low for requirement on machining accuracy; Can effectively reduce cost, improve installation efficiency.The internal diameter at the counterface place of breathing pipe and fixed scroll is less than the internal diameter of O-ring seals; External diameter is greater than the external diameter of O-ring seals; Make breathing pipe can reduce at the assembly precision at loam cake place; Improve the installation property and the processability of breathing pipe, the position accuracy demand of the mount grooves of O-ring seals also can reduce simultaneously, improves the processability of mount grooves.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
